ethyl 2-oxo-2-(3-(trifluoromethyl)phenylamino)acetate; CAS No.: 17738-86-2; ethyl 2-oxo-2-(3-(trifluoromethyl)phenylamino)acetate. PROPERTIES: This trifluoromethyl-substituted amino ester features molecular formula C??H??F?NO? with molecular weight 259.21 g/mol. Exists as a liquid. Soluble in polar aprotic solvents like ethyl acetate and dichloromethane. Boiling point approximately 130-135 C. Exhibits IR absorption for ester and amide groups. Thermogravimetric analysis shows decomposition above 180 C under nitrogen. Store at 2-8 C in sealed containers. May cause skin irritation and eye damage. APPLICATIONS: As a trifluoromethyl-substituted amino ester, ethyl 2-oxo-2-(3-(trifluoromethyl)phenylamino)acetate is used in beta-blocker synthesis. The ester group hydrolyzes to carboxylic acid, forming amide functionality. Also used in fluorescent probe synthesis, enabling conjugation via enzymatic hydrolysis. In materials science, it enhances thermal stability in polyaryl acid polymers due to trifluoromethyl substituents.
